On Suse Linux 10.0, I get e.g.:

cat t.c
#include <stdio.h>
#include <linux/ext2_fs.h>

gcc -c t.c
In file included from /usr/include/linux/ext2_fs.h:20,
                 from t.c:2:
/usr/include/linux/ext2_fs_sb.h:40: error: syntax error before âuid_tâ
/usr/include/linux/ext2_fs_sb.h:49: error: syntax error before âs_next_generationâ
/usr/include/linux/ext2_fs_sb.h:51: error: syntax error before â*â token
/usr/include/linux/ext2_fs_sb.h:56: error: syntax error before â}â token
